Project:Acquire and Install Unique Air and Pressurized Ozone Technology to Reduce Pathogens and Biological Loading of Processing Wastewater at a Tofino Fish Processing Plant

Company: Pacific National Processing Ltd, managed by Mainstream Canada

Industry: Salmon Farming

Location: Tofino, BC, west coast of Vancouver Island

Aquaculture in Canada FACTS•Canadian production value as of 2008: 2.29 billion dollarsIn 2008, BC production made up 54% of total Canadian production• BC production value : $1.23 Billion

FACTS•BC – 4th largest producer of cultured salmon in the world• 2008 BC Aquaculture Revenue - $1.2 Billion • 94% of production is Atlantic salmon

• Export value $ 857 M to 82 countries

more than 16,000 full and part time BC jobs in production and processing

One of the largest issues being the treatment of blood water and production waste from fish processing

Restrictions to Industry Growth

Blood Water Waste

Produced during fish harvesting and processingContains sea water, fresh water, salted ice and fish bloodAlso may contain

DirtFish entrailsViruses and Pathogens such as IHN

Must be treated and discharged

Treatment of Blood WaterDischarge requires

Reduction of suspended solids

measured as Total Suspended Solids (TSS) and Biological Oxygen Demand (BOD)

Reduction of Biological Oxygen Demand and Chemical Oxygen Demand

measured as Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD)

Disinfection of pathogens and other harmful agents

Treatment Options1. Dissolved Air Flotation (DAF)

Compressors, saturators, media and small orifices create bubbles which attach and float particles to the surface Problem: bubbles are relatively large resulting in inefficient flotation and removal of suspended solidsProblem: small orifices and media are easily clogged causing loss of performance and system failureProblem: does not treat bacteria or pathogens

Conventional Blood Treatment Options2. Aeration Chambers

Assist in reducing BOD and CODProblem: requires expensive and power hungry blowers to provide air supply

3. Settling PondsWastes are allowed to settle leaving clean water on surfaceProblem: requires a very large area and considerable time. Requires periodic clean-out

None of these processes disinfect the water

Disadvantages of UV disinfection treatment in waste water with high TSS, Organics and Colour

BLOOD WATER TREATMENT

“A new and innovative approach” Pressurized Ozone Disinfection

MASS Technology

Micro Air Separation System – MASS TechnologyDeveloped by Muddy River Technologies

Includes the proprietary Micro Bubble Generator ( MBG )

Intimate mixing of water and gasesCreating ultra fine bubbles (5 µm)Allowing maximum contact with suspended solidsUnprecedented ability to float suspended solids

Muddy River Technologies

Canadian owned and operated company based in Delta BCDesigns and manufactures proprietary technology for the water and wastewater industryFood Processing, Agriculture, Industrial Waste Water, Department of National Defense, Department of Fisheries and Oceans

Industries Served

Food Industry – Processing waste from a deli meat producerPretreatment of non hazardous wastewater – Processing grease trap wastewater, septage and industrial wastewater Canadian DND – de-oiling bilge water DFO – disinfection before discharge. Water from scientific study aquariums at the Pacific Biological Station

Stage One – Suspended Solids Removal• Micro bubbles injected into waste• Highly efficient removal of suspended solids which are floated

and removed• Reduction in Biological Oxygen Demand (BOD), Chemical Oxygen

Demand (COD) and Total Suspended Solids (TSS)

MASS Treatment

Stage One Standard MASS System

Stage Two – Disinfection and Clarification

Ozone is introduced at the feed stream, passes through the Micro Bubble Generator and dissolved under pressure Oxidizes remaining blood protein Removes remaining colour Kills or deactivates bacteria, viruses and other micro-organisms present

Stage TwoOzone MASS

The Final Product

Suspended solids removed Bacteria, viruses and other pathogens deactivatedWater clarified and ready for discharge

Final product Initial Blood Water

Salmon Aquaculture – A Growing Industry

New and more efficient methods of wastewater treatment are needed to support industry growth and meet environmental standards

Salmon farming is a viable long term industry and an important contributor to the Canadian economy

Six Treatment Stages

1. Untreated blood water2. Coagulant added and pH lowered3. pH adjusted4. Flocculent added5. Primary MASS effluent6. Ozone MASS effluent (clarified & disinfected)

The MASS Technology and Salmon Production

The MASS technology provides an efficient and cost effective solution to the problem of treating fish processing waste water

The MASS technology is suitable for all Canadian processing plants and all types of discharge systems

The MASS technology is appropriate to meet environmental wastewater standards
